Boss punched my timecard out, WTF?

[jk3a]

I work as an assistant golf professional at a small country club. We still use a traditional time card system where you have to take your card and run it through a machine when coming and going.

I have a fairly unique situation in which I get paid which is fairly common in my industry. I get paid a base salary regardless of the hours I work in a week. Any hours over 40 in a week, I am paid 1/2 time for. The 1/2 time wage is simply 1/2 of what my hourly wage would be according to my base salary and a 40 hour week. It's not much, maybe $6 dollars an hour or so, but it usually adds up to around $2500 per year because of some of the busy months.

I have been at this position for 2 years, and was told by my boss that I'm allowed to stay on the clock to play and practice golf so long as I was scheduled to be there that day. This also is very industry standard. For the previous 2 years, there has never been an issue made about this until yesterday.

After my shift, I played for about 3 hours. When I returned to the clubhouse to time out, I noticed my time card was stamped already for shortly after my "shift" ended a few hours prior. I was already over the 40 hour mark for the week, so a small amount of money was "taken" from me.

I called our general manager (not my direct boss) to ask him if he did it, and he said "yes." I tried to explain to him that he can't do that, but my argument was dismissed fairly quickly. I contacted my boss, who was very upset about it, and said that he would take care of it on Tuesday(tomorrow). We are closed today.

For the record, the general manager is the extreme version of a micro-manager. I'm sure many of you know the type. What it do? Do I have any options outside of just "letting my boss handle it" or quitting?
