Posties aren't striking because they get shit pay, they're striking because of Royal Mails latest PROPOSALS which will affect pay and conditions for the future.
It will also affect you all in some way or another which you don't seem to appreciate yet. For example, from next week our office is being forced to start 1hr 15mins later, which means mail will be even later getting out.
Also they're closing more Post Offices, and putting up the price of stamps.
