Do you need to wear your uniform for a McDonald's Meeting?!
Answers:
You only have to wear the uniform if you're manager asks you to. If you're scheduled to work after the meeting it would be a good idea to go ahead a wear it. That way you can clock in and get right to work. If you're off that day or if you are scheduled to come in later on that day then no you don't have to wear the uniform.
*I'm a former manager of a McDonald's so unless this information has changed within the last 10 years then what I've stated is true.
its your supervisor's choice usually
ask them what is expected, if its expected to wear your uniform, wear it, otherwise, feel free to wear your normal clothes
If you are planning to work afterwards Yes, If not I do not see why you would have to, you are not going to have to deal with customers
it is up to the company ask them before you go to be safe
