1. Managers shouldn't be pressuring employees not to take breaks. A schedule should be created so everyone isn't on break at once and there is sufficient staff to cover.
You don't say that managers won't allow you to take breaks. So take your break.
They don't have to pay you for your breaks. If you work from 12 pm to 10 pm and don't take breaks, which is wrong, then you have worked a 10 hour day and should be paid 8 hours regular time and 2 hours time and a half overtime.
Adding your breaks to the end of your shift doesn't make sense as you aren't paid for them.
If you work 12 - 10, and take your half hour break, then you should be paid 8 Reg and 1.5 OT
2. I don't understand...resignation means you are quitting. You don't have to give 2 weeks notice to your employer but don't expect a reference if you leave them in the lurch. Employers, unless they are laying off due to lack of work (depending on situtations) or if there is just cause, need to give notice as per this.....
•After three consecutive months of employment – one week’s pay;
•After 12 consecutive months of employment – two weeks’ pay;
•After three consecutive years – three weeks’ pay, plus one week’s pay for each additional year of employment to a maximum of eight weeks.

Keep in mind common law will come into play after 3 years.
3. Nope if you work Tuesday or Thursday it isn't overtime unless you have already worked 40 hours that week. However if you do work and work more than 8 hours then you will be paid overtime for the hours over 8.
Everyone who is employed should know the Employment Standards website. There is also a toll-free number where you can ask questions without using your name. Explain the situation and they will advise you.
