Having joined the primary teaching profession in the last few years after a management-level career elsewhere, I would say that there is a huge amount of work needed to achieve even a baseline of competence day-to-day. You just can't blag it or have an off-day (or even an off-hour) when you are in front of the children. There is also a constant sense of being observed and given criticism that does require a little getting used to. Self-reflection is part of the job and there is no lesson that cannot be evaluated and improved. We must plan for as many eventualities that we can foresee and then react calmly in the moment to the one we didn't. I wasn't and am still not an SEN expert but I have worked hard getting to know the individual and nuanced needs of the children in my class and attended multiple courses to give me professional support to do this.
Explaining that to non-teachers is a bit like parents explaining to non-parents what it is like, so the conversations can end up sounding condescending or self-pitying when there is a huge amount of joy and some perks to the profession (just as there is to being a parent.)
I only have experience in a few fields of work outside of teaching and I am sure (e.g.) hospital work is similarly relentless, particularly in some roles. There are also plenty of jobs where the hard work is not offset with moments of joy, laughter or perks such as school holidays and lovely drawings of yourself.
I have had a lovely summer with my children and that is the payoff for not being able to attend even one of my daughter's settling in sessions for Reception, or my son's music concert. They know this but they will still ask me if I can come, and that is difficult. I fully appreciate what I do have and encourage them to do the same. They also came in and helped me set up my new classroom over the summer.
The other factor in recent times is lockdown, during which the government and certain media have encouraged a narrative of lazy teachers having "two years off". Certainly many schools were initially unprepared and took a while to put online schooling in place - mine was ready to go from day one and we taught live from 8.45-3.15 every day as well as having a large contingent of vulnerable/keyworker children on site, but my children's school didn't teach live for the first few weeks at all, and then only one session a day, so I can see there was a big variance. The government could/should have redeployed Ofsted or created hubs to link schools together and share expertise and equipment access as quickly and efficiently as possible, but it seemed to suit them better to lay blame on individual class teachers who had little control over their school's handling of the situation. This has filtered nicely through to MN and other internet sites.
In all honesty I find the public comments one of the hardest things to take about my job because it feels like there's no way to respond without opening up a conversation about "who works hardest" and as others have said, it shouldn't be a race to the bottom. All I can say is that to me, being a teacher is a responsibility and a privilege that I take seriously and I have yet to meet a teacher who doesn't treat the profession with equal gravity.
