Isn't totting the practice of taking something from the rubbish to sell on? It doesn't really matter whether it's perceived to be of value, just anything that you could find that you could subsequently sell.
In this case, I think the charges are reasonable - the perception, based on the information the employer may have at the moment, is that the moving of the deodorant was for totting purposes. (Wouldn't going through the rubbish at the back of a truck be misconduct anyway? Surely there is a health & safety risk by going through rubbish, regardless of intentions? You don't know what else is in the rubbish that could cause you personal harm, and what if the machine was activated while you were rummaging? The employer can amend the disciplinary charge as the facts emerge, if appropriate in the circumstances.)
Once you have your chance to explain the reasons, obviously I don't think any disciplinary charges should be brought for totting, but that shouldn't stop the employer from contemplating disciplinary charges. They should ideally be interviewing you as part of the disciplinary investigation, not simply bringing charges without you having had a chance to explain the circumstances though.
As for pay on suspension, this is an area that often causes confusion. Only if the contract allows for suspension without pay is this permitted. (Even then, an employer should consider requests for pay where there may be financial hardship to the employee.) Whether to suspend with or without pay is then entirely at the discretion of the employer, and it should be based on whatever grounds they care to apply, as long as this is nothing associated with suspicion (or otherwise) of guilt against the disciplinary charges; it can be sensible to set out the circumstances where suspension may be without pay, such as where there is a perception that the employer has suffered financial loss, or there is a risk of this in the future.
Suspension without pay during a disciplinary investigation is not a disciplinary penalty in itself (although this can, separately, be a disciplinary penalty where provided for in the policy - a useful option to provide something between a warning & dismissal), and should neither be used for this purpose or seen as being used for this purpose. Ergo, if an employee is subsequently found not to be guilty of any disciplinary offence, it would normally be appropriate to reimburse them for any loss of earnings during suspension without pay.
