[1] During the leadership of Anuruddha Padeniya the GMOA was heavily politicized becoming affiliated with the Sri Lanka Podujana Peramuna and the Rajapaksa Family.
The GMOA frequently clashed with the 2015-2019 government, including organizing multiple strikes over several issues.
OPD services and medical clinics of several government hospitals were crippled due to the strike but was ultimately considered a failure as many hospitals continued normal work and over 200 Trade Unions opposed the GMOA strike and accused them of attempting to return Mahinda Rajapaksa back to power.
[11] Following strike action and discussions with officials of the Finance Ministry, Health Ministry and the GMOA, contradicting statements were released by the Health Minister stating that income tax imposed on specialist doctors will be reduced to 15% from the normal 24%; while the Finance Minister has refuted the Health Ministers statement stating that the income tax rate for 24% based on the Inland Revenue (IR) Act was not changed but provisional relief granted by changing the method of calculating tax imposed on specialist doctors.
[14] With the Rajapaksa's return to power in 2019 the GMOA and Padeniya were major endorsers of the transition to organic agriculture ignoring scientific evidence and pushing mythical claims of ancient Sri Lankans having lifespans of 140 years blaming the decline to modern agricultural technology as well as spreading claims of Sri Lankans being the largest consumer of what he described as "poison".
